What do you mean excuse suicide? There's nothing wrong with suicide. What's wrong are fucked up cultural norms that have been shoved down people's throats that say people have to suffer to the bitter end no matter what because of some fucked up religious bullshit. I can think of lots of reasons for self-terminating early and not one for suffering needlessly. The guy had the stones to go out on his own terms, that's pretty goddamned brave in my books.

"During times of universal deceit telling the truth is a revolutionary act."

Shooting himself in the chest instead of the head so his brain could be analyzed for CTE?! That's fucking brave. Shooting yourself in the head is pretty much guaranteed a painless death, but it's easy to screw up shooting yourself in the chest.

Not to excuse suicide, but it seems likely this was triggered by the physiological damage to his brain.
